Width of smallest plot is 5.18 m Length of smallest plot is 8.15 m Slope: 0.25-2 % . Shape: Uniform Details of direction of cultivation: Right angles Width of Bare Strip around plot: None Width of Discard Strip around plot: Variable ... Details of homogeneity of the plots: See two papers by McGrath & Lane describing a model for physical dispersion of soil particles by cultivation on these plots

b) Details of replication, randomization and controls

The experiment has a randomized plot design. There are control plots described as follows: Inorganic fertilizers only - double reps compared with 'organic' treatments. Limited back-checking of Walkley/Black and Tinsley measurements
